There is no privileged link between kinds and essences early in development

Area of Science:

• Cognitive Development
• Developmental Psychology
• Social Cognition

Background:

• Dominant theories propose that generic language, particularly for social categories, promotes essentialist interpretations.
• Essentialism suggests that categories, or 'kinds,' possess underlying, immutable essences.
• The role of generic language in shaping children's category understanding, especially regarding essentialism versus flexible causal structures, requires further investigation.

Purpose of the Study:

• To investigate whether children infer essences from generic language or adopt diverse causal structures.
• To examine how children's interpretations of novel social categories vary based on property type (biological vs. cultural) and age.
• To determine if generic language uniquely leads to essentialist beliefs or if children exhibit flexible reasoning.

Main Methods:

• A preregistered study involving 240 American children aged 4 to 9 years.
• Children learned about a novel social category described using generic statements featuring either biological or cultural properties.
• Assessed children's inferences about the causal structure underlying the category (essentialist vs. socialized).

Main Results:

• Generic language prompted children to perceive properties as nonaccidental.
• Younger children (4-5 years) primarily inferred a socialized causal structure.
• Older children (6-9 years) demonstrated flexible interpretation, inferring essentialist or socialized structures based on property type.

Conclusions:

• Children exhibit early-emerging flexibility in category representation, not solely relying on essentialist inferences from generic language.
• The type of properties (biological vs. cultural) influences children's causal attributions for categories.
• There is no privileged, automatic link between generic language, kinds, and essentialism in children's developing social cognition.
